This is an old thread but for anybody new looking for answers this is set in the loop setting, you can set the routing either to pre or to post.
From the manual: "Press the Presets button to enter Edit Mode. Use the left arrow on the Nav Disc
to navigate to the LOOP screen. Set Routing to Pre by turning the Presets knob."
If it's set to pre the loop will change with the presets and set to post the loop will not change!
